METHODS: Autologous whole blood was injected into the vitreous cavity of albino rabbits after canalization, thus induced experimental PVR model. Concentration of PDGF.

采用眼穿通伤+注血法制备PVR模型，进行眼底及常规组织病理学观察，ELISA法检测玻璃体中血小板源性生长因子的浓度，用免疫组织化学方法观察增生膜与血管内皮细胞表面血管细胞粘附分子-1（VCAM-1）及细胞间粘附分子-1（ICAM-1）的表达。

Therefore, the purposes of this paper are on, firstly, the possible difference of secret of vasoactive substances from pulmonary artery and aortic artery endothelial cells; secondly, the regulatory effect of pulmonary microartery endothelial cella on the movement of pulmonary artery.

所以本文的研究目的为：1研究肺动脉内皮细胞和主动脉内皮细胞分泌血管活性物质的可能差异：2研究肺微动脉内皮细胞对肺动脉血管运动的调节作用；此外，基于我室以往对吸烟和肺血管反应性的研究。

Further more, hoechst stained caveolin-1 expressing GH3 cells showed chromatolysis and the character of cell and cell apoptosis was confirmed by TUNEL assay. To obtain this data, we hypothesize that caveolin may play a role in bromocriptine induced GH3 apoptosis.

在转型48小时后，GH3细胞表现外源性caveolin-1，其细胞呈现萎缩形态且其细胞核呈现计画性死亡的核体分解现象；但表现EGFP的细胞仍维持正常形态。

It is concluded that (1) there are no relationships between fusion rate and relativeness of the recipient cytoplasm to nucleus donor cells,(2) cytoplast of the goat MII oocyte can support the preimplantation development of SCNT embryos reconstructed with nucleus from other species,(3) the blastocyst rate of close relative inter-species SCNT embryos is higher than that of distant relative inter-species SCNT embryos.

由此结果得出以下结论：(1)山羊M II期卵母细胞胞质与供核细胞之间的亲缘性不影响两者的融合率；(2)山羊M II期卵母细胞的胞质能支持异种间体细胞核移植胚的着床前发育；(3)亲缘关系近的种间核移植胚的囊胚发育率高于亲缘关系远的种间核移植胚的。

Our results show that:the disbalance of Thl/Th2 caused by keratinocvte after UV exposure probably play an important role in the pathogenesis of potodermatitis. Of course, the further experiment is necessary.

为下一步工作提供理论和实验依据，照射后角质形成细胞产生细胞因子致T细胞亚群失衡与光敏性皮炎的相关性有待于进一步的体内外实验证实。

Objective To explore the in vitro isolation of β2m(superscript -)/Thy-1(superscript +) bone marrow-derived liver stem cells which bear double features of stem and liver cells from bone marrow stem cells as so to provide suitable donor cells for the treatment of liver diseases by cellular transplant.

目的 尝试从骨髓干细胞中分选出具备干细胞和肝细胞双重特性的β2m/Thy-1骨髓源性肝干细胞亚群，为细胞移植治疗肝病提供合适的供体细胞。

In order to investigate cellular and molecular interactions between symbionts and their host endoderm cells, an homogeneous population of endoderm cell is required.

为了研究共体与宿主內胚层细胞之间分子与细胞的交互作用，必须要有一群同质性的內胚层细胞。

The organic cells that have potential excitation can change the penetrability of Na~+ if they receive stimulation from external ,then Action potential occurs.

对组织细胞进行刺激可以改变可兴奋细胞对Na~+或Ca~(2+通透性，从而产生动作电位，使其内部的Na~+、K~+离子通道发生变化引起内部环境的改变，最终改变细胞的状态。

The tumor is lobulated under microscope, some immature Sertoli cells were arranged as either amorphous plaques, funicular, broad beam, nest, solid or hollow tubules; Leydig cells existed individually or in clusters, and their cytoplasm was abundant and eosinophilic.

镜下肿瘤呈分叶状，有不成熟的支持细胞排列呈片块状、不规则形或条索状、宽梁状、巢状、实性或空心的小管；莱迪细胞呈单个或簇集存在，细胞浆丰富且嗜酸。

KIR bind corresponding HLA-Ⅰmay hame four results followed:1、When inhibitory KIR bind HLA-Ⅰand there has no activatory KIR bind it,cell isn\'t dissolve because inhibitory signal access was done;2、When activatory KIR bind corresponding HLA-Ⅰand there has no inhibitory KIR bind it,form activate signal,lead cell dissolve.3、If activatory or inhibitory receptor both bind HLA-Ⅰ,both signal access is make done,when activatory signal play the main role,NK cell still actived,lead target cell dissolve.4、If activatory or inhibitory receptor both bind HLA-Ⅰ,both signal access is make done,when inhibitory signal play the main role,or both signal access don\'t play,NK cell do not make effect.this is NK cell recognice nomal tissue.

与活化型KIR受体相比，抑制型KIR受体与HLA-Ⅰ类抗原结合的亲和性更强，当抑制型和活化型KIR受体识别和结合同一HLA-Ⅰ类抗原分子时，以抑制作用为主。KIR与相应HLA-Ⅰ结合后可能产生以下4种情况：①当抑制型KIR与HLA-Ⅰ结合而无活化型KIR与HLA-Ⅰ相互作用时，因抑制信号通路启动而不产生细胞溶解；②当活化型KIR与靶细胞表面的相应HLA-Ⅰ结合同时无抑制型KIR与HLA-Ⅰ的相互作用时，形成刺激信号通路，导致靶细胞溶解。
